A series of 200 miniature artworks are being auctioned as part of a fundraising initiative to raise awareness of hepatitis C.
Damien Hirst, Harland Miller and Marc Quinn were among some of the artists who anonymously contributed postcard-sized works of art.
Bidders were invited to put in offers on the artworks during the online auction and though the artists were meant to be revealed last night, the auction has proved so popular it has been extended until 5pm today.
Money raised from the auction will be donated to The Hepatitis C Trust.
